This is Matienso. He loves to drink Mate all day cuz it keeps him awake.
I've been drinking mate almost everyday to keep me awake since Leo likes to wake up in the middle of the night to drink milk and then wakes up at 7 am to play. This first time I tried it I was like "aagghhh". We were living in Texas and my hubby got a care package from his parents with mate and the necessary thingies to drink it. But now I drink it a lot, mostly to cut back on the coffee.
This dude drank mate too.
